Unified Physics/Fluids provides an introductory treatment of basic fluid principles as well as others elected topics. The materials are organized around a number of fundamental concepts of modern technology: differential forces, flow rates, opposition to flow, energy storage, time constants, impedance matching and resonance. The purpose of this organization is to provide a foundation for the study of several related technologies. The instructional material is presented in an action-oriented format combining many of the features normally found in a textbook with those usually associated with a laboratory manual.

This manual, along with the others in the Electromechanical Technology Series, is the result of six years of research and development by TERC, a national nonprofit, public service corporation with headquarters in Cambridge, Massachusetts. It has undergone a number of revisions as a direct result of experience gained with students in technical schools and community colleges throughout the country.
